The reproductive performances of aceh cattle in extreme environment is supported by its reproductive capacity system. This research wasconducted to study there productive system of aceh cattle by examining morphometric and histological characteristics of aceh cow ovaries duringthe estrous cycle. Fifteen Aceh mature cows during estrous cycle, with 200-300 kg of body weight were used in this study. Samples were takenfrom slaughter house in Banda Aceh Municipality, Aceh Province. The ovaries were observed morphometry, then fixed in Bouin solution andprocessed histologically. Ovaries were stained with hematoxylin and eosin to observe the morphometric characteristics of ovarian histology. Thedata obtained are presented in the form of tables and figures, and analyzed descriptively. Aceh has a cow ovarian morphometry and histologycalstructure during different phases of the estrous cycle occurs.____________________________________________________________________________________________________________________Key words: histology, ovary, aceh cattle, estrous cycle

The aim of this research was to observe intestinal glands histology of duodenum from native chicken, pigeon, and duck. Samples used are duodenum from 3 native chickens, 3 pigeons, and 3 ducks with undifferentiated of sex and weight. Fowl was slaughtered, duodenum were taken out then proceeded for histology method using parraffination and stained with hematoxylin-eosin. Histological observation include the density and morphology of intestinal glands. Data were analyzed descriptively. The results showed that the intestinal glands histology differ among native chicken, pigeon, and duck but the morphology of intestinal gland was similar that was simple tubular. The number of intestinal glands in native chicken and pigeon almost similar and found in high density but lower than that found in pigeon. This difference assumed to be correlated with type and concentration of feed.

The aim of this research was to determine the anatomy and histology of pancreas of water monitor lizard (Varanus salvator). Two pancreas were used in this research (a male and a female). Water monitor lizard was euthanized using chloroform and subsequently necropsied to collect the pancreas. The pancreas was washed in 0.9 % NaCl solution. Anatomical observations were carried out including location, shape, and color of pancreas, also the length and weight measurements. Then, pancreas was fixed with 4% paraformaldehyde for 7 days to proceed to histological preparation and hematoxylin eosin (HE) staining. The results of the anatomical observations showed that pancreas of water monitor lizard have two lobes, dorsal lobe (splenic lobe) and ventral lobe (duodenal lobe). Dorsal lobe which was in oval form adhered with the spleen, and ventral lobe was located in the cranial of intestines with the form of long spherical. Both of pancreas lobes were white-yellow color with the length of 1.45Â±0.64 cm (dorsal lobe) and 7.00Â±0.42 cm (ventral lobe). Weight of dorsal lobe was 0.15Â±0.01 g and ventral lobe was 6.35Â±2.30 g. The histological observations found the acinar cells, ducts, and blood vessels in both of pancreas lobes. Additionally, the similar structure of Langerhans islet only found at the ventral lobe of pancreas. In conclusion, pancreas of water monitor lizard consists of two lobes which located differently. Ventral lobe is larger than the dorsal lobe. Both lobes have similar histological structure except the Langerhans islets are only appeared in the ventral lobe.
